    SubjectRe: [PATCH v2 15/30] xfs: Define usercopy region in xfs_inode slab cache
    One thing I've been wondering is wether we should actually just
    get rid of the online area. Compared to reading an inode from
    disk a single additional kmalloc is negligible, and not having the
    inline data / extent list would allow us to reduce the inode size
    significantly.

    Kees/David: how many of these patches are file systems with some
    sort of inline data? Given that it's only about 30 patches declaring
    allocations either entirely valid for user copy or not might end up
    being nicer in many ways than these offsets.
